Highfather's History
Highfather is the ruler of New Genesis, a powerful New God who seeks to bring peace to the Multiverse and destroy his eternal enemy and brother Darkseid.
Death of the Old Gods
Izaya is the firstborn of the Old God Yuga Khan, living as a mud-grubber alongside his wife Avia and his brother Uxas, constantly suffering the abuse of the all-mighty deities who paid little attention to their devout worshippers. He saw his brother's blaspheming as a way to bring divine wrath upon his family and the world, but Uxas believed this would be a good thing, deciding to start a war among the Old Gods.
Dragged into his brother's war, Izaya fought alongside Uxas against the Gods and their allies, among them being their own father. Using the Anti-Life to revive the Gods Uxas killed, Yuga Khan clashed against his sons and was ultimately murdered by Uxas, ending the life of the Old Gods.
Trying to run for Avia's life, he stopped at the wounded body of the lord of the sky. Izaya put his faith in the sky God and begged him to save her, but both she and the God were too far gone. But even as the sky deity died, taking Avia with him, he bestowed upon Izaya the last vestiges of his power, transforming him into a New God.
Izaya faced Uxas, who reacted with disdain at the idea that Izaya would steal power from the Old Gods as well, but Izaya responded that their powers were gifts, that they were both New Gods and pleaded with him to join forces in the light, but this only filled Darkseid's heart with more contempt, so he destroyed the entire planet, leaving the two of them as the only known survivors.
Eons later, Izaya built the utopia of New Genesis over the ruins of their previous world and took the name Highfather, taking upon himself to destroy his brother and free all creation from his menace, igniting an everlasting war between both.
At some point Highfather conceived a son with an unknown spouse who was also killed by by Darkseid in a failed unification attempt, which ultimately ended in the long spanning conflict between New Genesis and Apokolips. In the end he was forced to trade his only progeny for Darkseid's own in a new found peace treaty between New Genesis and Apokolips. While initially against such a treaty with his hated brother, a desperate Izaya ventured into what remains of the Source Wall. Seeking out the fabled Source Shard, part of the original wall before the Old Gods died for answers.
Instead he was sundered between his moral center and a new heartless self, his humanity being divested among the now cold and calculating Highfather persona and an abstract extension of himself called Infinity Man. Who would forever bare his love, loss and all their shared regrets.
Early Meetings With Superheroes
Highfather sent his son Orion to Earth 0 in quest of a great menace he foresaw through The Source Wall, a threat he revealed was posed by the last Kryptonian due to his tremendous power being a danger to that universe.
Some time later, Orion brought an Amazon, a Goddess queen, a mortal and her baby child to Highfather's presence after escaping a dangerous being from Earth. He placed Diana into a coma for three days so her sustained wounds could heal, while reprimanding Orion for bringing foreigners to New Genesis. He then ordered Orion to take the infant, a command he reluctantly followed at first, but his rebellious nature took the best of him and once again disobeyed his father, teleporting everyone back to Earth away from New Genesis, an outcome Highfather knew would unfold.
Godhead
Highfather visited the Source Wall alongside Metron in search for a weapon capable of ending the war against his brother once and for all, the Life Equation. They interrogated the imprisoned Relic, discovering that someone has crossed the wall and tampered with the Life Equation through the power of the Lantern Rings. To the end of gathering the Equation for himself, he had the Council of Eight seek out and recover the seven rings that consist of the Emotional Spectrum.
He commanded Hyalt to modify his scepter in order to channel the energy of the rings, but they proved insufficient to harness the power of the Equation, so he decided to search for the one who caused the wall breach, the White Lantern, while also deeming the Lantern Rings too powerful for mortals to use and commanded his Council to retrieve them all.
After discovering the White Lantern's location, Highfather followed him to win his trust by giving him a means of "saving" him from his uncontrollable power which was tampered by the Templar Guardians, offering him a means of saving his life on New Genesis, an offer he agreed to while also taking Carol Ferris with him.
Highfather then convinced Kyle to willingly give him full control of the Life Equation, opening a mental backdoor to the Equation by cutting off Kyle from utilizing it, and stranded both him and Carol in the ruins of Old Genesis. The Equation finally his, he and Bekka traveled to the planet of Muz and successfully transformed the entire inhabitants into a mighty New God army.
Once the Council of Eight completed the capture of the ring wielders, he proceeded to inform his subjects of his plot for them, planning to convert both the Lanterns and the humans alongside their defenders on Earth into loyal soldiers for their war against Apokolips.
The numerous Corps locked at the Singularity Stockade, Highfather offered the Lantern Indigo-1 an opportunity to ally with them, surrender the Corps and the Indigo Tribe will be spared, one she gladly accepted. However, when he was about to convert the Green Lanterns, his Council member Malhedron turned against him, proclaiming he won't serve a tyrant while saving the Lanterns from his leader by teleporting them away. Frustrated, he left Uggha to deal with the insurrection against his authority. Kyle and Carol managed to return to New Genesis and take the White Ring back, but it would not channel the Life Equation as Highfather remained fully in control of it, proclaiming he is one with the Equation before getting rid of them with his power.
Highfather was preparing for the invasion when Lantern Sinestro arrived to offer him a truce, surrender against him and the New Gods will live, but Highfather only mocked him, considering him an inferior being. Overpowered, Sinestro escaped through a Boom-Tube, but Highfather decided to ignore him to focus in his invasion of Earth.
Unknown to him, Sinestro tampered the Boom-Tube's coordinates in order to summon reinforcements which came in the form of the Source Titans, ancient beings from the Source Wall revived by the Black Hand who forced Highfather to defend New Genesis from the titanic threat. He desperately tried to transform them to their ranks with the Life Equation, but the beings were beyond his scope and he was powerless against them. That plus the Lantern Jordan's claim that he was becoming the very Darkseid he despises, made Highfather realize the atrocity of his actions.
He regretfully returned the Life Equation to Kyle's possession, who immediately managed to free New Genesis from the Titans, but was too late to save the flying city which was too damaged to remain sustainable on orbit. Fortunately, Lantern Jordan and Saint Walker combined their power to prevent the city's impending disaster and save all the surviving New Gods. Highfather sincerely apologized for the pain he caused, and promised he will never again become the very thing he abhors, while also declaring he must not only restore New Genesis' structures, but his own people's trust as well.
